The roof of IKEA in Åsane outside Bergen covers 22,000 m2 and has been covered with plants since 2011. (Ref. 1) The green roof promotes biodiversity, cleanses the air from pollutants and acts an important flood prevention measure in the region, as Bergen experiences a lot of rainfall and is expected to receive more as a consequence of climate change over the coming decades. (Ref. 3,5) The roof has attracted a lot of birdlife, including endangered species. (Ref. 2)

Focus
Creation of new green areas
Project objectives
This NBS aimed to achieve the following:
- Address expected climate change impacts of increased flooding (Ref. 5)
- Capture CO2 emissions (Ref. 3)
- Dampen the visual impression of the large building using green infrastructure (Ref. 3)
Implementation activities
Creation of 22,000 m2 green sedum roof (Ref. 1,3,5)
Regular maintenance - After the delivery in 2011 the roof faced large problems. During the first winter, a lot of the plants died. Studies were initiated and two plant consultants tried different solutions. After a year of study and comprehensive plant trials on the roof it was concluded that sedum roofs in Bergen require very good drainage and therefore put high demands on the growth substrate.
In the summer of 2013, the roof was re-established with new substrates and new plants and it now appears as a beautiful, thriving green roof. (Ref. 1)
Climate-focused activities
Climate change adaptation:
- Implement green walls or roofs to lower indoor temperature and provide insulation
- Implement sustainable urban drainage infrastructure (e.g. to make space for water)
Climate change mitigation:
- Install vertical or horizontal artificial surfaces that help with carbon storage and cooling

Details on the roles of the organisations involved in the project
Local Government: Bergen municipality had certain demands regarding the establishment of a new IKEA warehouse in Åsane, in order for it to be accepted in the proposed area. This included the installation of a green roof on top of the warehouse (Ref. 5).
Private Sector: IKEA has been largely involved with the installation of the roof. The company Bergknapp has been responsible for installing/planting the roof and choosing suitable plant species (sedum). (Ref. 1, 4)
